Ray Kobayashi, Realtor & General ContractorRaymond Kobayashi, Jr.

Realtor & General Contractor

For Ray Kobayashi, real estate investment and sales has been a way to extend his building construction skills to allow people to be able to afford their own homes.  Most of the sales by the company are for brand new homes that he has designed and built.

Ray was a Realtor before he became a building contractor.  His first home was built 38 years ago, an 880 sf package home, which he built for $12,000 and sold a year later for $24,000.  With this kind of quick profit, Ray decided that construction was his calling

He so enjoyed the experience of building his own home, that he obtained his contractor's license on December 6, 1974 and established R.K. Builders, Inc, his construction company.  R. K. Builders, Inc. has built over 450 residential homes throughout East Hawaii, a 20-unit townhouse (Kawili Regency), an 18,000 sf warehouse in the Shipman Industrial Park, 16,200 sf warehouse in Pahoa and customized several shops at Prince Kuhio Plaza.   His masterpiece is Kaiwiki Road, which is a three-story five-bedroom, 4 ½ bath luxury home with custom local woods (koa, eucalyptus, mango, sugi pine and ohia) on walls, ceilings and floors.
